VIIRS/JPSS1 Active Fires 6-Min L2 Swath 375m V002

The Visible Infrared Imaging Radiometer Suite (VIIRS) Active Fires (VJ114IMG) Version 2 product is produced in 6-minute temporal satellite increments (swaths) at 375 meter resolution from the VIIRS sensor aboard the NOAA-20 satellite. This product is designed after the Terra and Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Thermal Anomalies and Fire data products to promote the continuity of the Earth Observation System (EOS) mission. This data product can enable users to understand the location and intensity of fire events as well as thermal anomalies.

The VJ114IMG product includes 25 science dataset variables to analyze key factors in fire detection, including atmospheric conditions (e.g., radiance, solar zenith angle, brightness temperature) and fuel type for the event. The fire mask variable in the VJ114IMG product is the primary variable and can be used to identify fires and other thermal anomalies such as volcanoes.

Each swath of data is approximately 3,060 kilometers along track (long) and 3,060 kilometers across track (wide). The VJ114IMG product is also used to generate higher-level fire data products.

Use of the [VJ103MODLL](https://doi.org/10.5067/viirs/vJ103modll.021) data product is required to apply accurate geolocation information to the VNP14IMG Science Datasets (SDS).
